The United States Patent and Trademark Office defines a trademark as, “a word, phrase, symbol or design, or combination of words, phrases, symbols or designs, that identifies and distinguishes the source of the goods of one party over those of others.”
A service mark is essentially the same except instead of identifying a good, it identifies the source of a service. Customary practice, however, is to refer to both trademarks and service marks as “trademarks.”
Note that a product or service can have more than one trademark associated with it.
